Abstract

La présente invention concerne une pompe d'acheminement de liquide hautement sécurisée et conçue pour éviter, de manière fiable, tout écoulement libre de fluide lors du montage et du retrait d'un tube d'acheminement de liquide sur/depuis la pompe. La pompe d'acheminement de fluide est pourvue d'un mécanisme de serrage coulissant capable de fermer ou d'ouvrir un tube (40) d'acheminement de liquide au moyen d'un élément de serrage, un mécanisme de soupape capable d'interrompre l'écoulement de liquide dans le tube (40) d'acheminement de liquide par compression dudit tube (40), et un mécanisme de verrouilage pour permettre au mécansime de serrage coulissant et au mécanisme de soupape d'être actionnés de manière verrouillée uniquement par actionnement de la manette (23). Pendant une série d'actionnement de la manette (23), au moins l'une des soupapes (14A, 14B) du serrage coulissant (30) obture systématiquement le tube (40) d'acheminement de liquide de manière à empêcher totalement tout écoulement libre du liquide dans ledit tube (40).
